[Libguestfs] Offline virtio installation on Windows 2012R2

[Nikos Skalkotos]

Hello Richard,

Thank you for the quick reply!

I used this:

diff <(hivexregedit --export HIVE_1 \\) <(hivexregedit --export HIVE_2 
\\)

to debug my python registry update code.  I'll also check virt-diff and 
I'll let you know if I have any news.

Nikos
